Adding `rubocop-capybara` as a required extension in configuration breaks build

[vietqhoang]

Adding rubocop-capybara to the "required extensions" list in .rubocop.yml configuration file breaks the build on CodeClimate.

A snippet of the require list in the .rubocop.yml:

require:
  - rubocop-capybara
  - rubocop-rails
  - rubocop-rspec

A screenshot of the build error:

Our CodeClimate setup is using the beta channel. Running rubocop locally executes without issue.

The expectation is for the CodeClimate to run successfully.

The output log of the CodeClimate error:

Just an aside question: are there any environment variables present during the build process which can be used to determine the environment is CodeClimate? A cursory Google search didn't yield anything.

For the time being, in order to not roadblock my end, I was thinking to conditionally exclude rubocop-capybara using some preprocessing and adding a conditional to check for the environment variable.

[vietqhoang]

Having rubocop-rspec_rails department in the require on the rubocop config breaks the Codeclimate engine.

The reason for the inclusion of the department is that starting with Rubocop Rspec major version 3 many of the departments (Cabybara, FactoryBot, etc) have been extracted out of the dependency.

See the release: https://github.com/rubocop/rubocop-rspec/releases/tag/v3.0.0

And the specific changes which extracted out Rubocop Rspec Rails: rubocop/rubocop-rspec#1830
